Please make sure you're using the latest build of gretl from
http://gretl.sourceforge.net/win32/
I think that what you describe was a temporary problem in CVS.

Can you tell us precisely what tests you are doing? I tried the
following and could not provoke a problem (or find any evidence of
memory corruption using valgrind):

Gretl crash

Hello,
A problem occurs when I try to run a unit root test (ADF) with constant and
trend with the attached file. I am running the last version under WinXP. The
data is compiled as panel data.
Please what is wrong?
Many thanks,

Drop permanently observations
by Giuseppe Vittucci
Here is my problem.
I need to drop *permanently* observations.
The command smpl (--restrict) simply creates a sub sample but it does
not change the dataset range.
This causes the full range to reappear each time I use smpl --full in
the loops.
And I cannot save a restricted version of the dataset and then reopen it
cause I loose the session (in particular matrices, vectors and scalars).
Is there a way to really drop observations? I need the "reverse" of
addobs.
Thanks

Restricted VAR estimation

Hi,
What is the best way to estimate in Gretl restricted VAR?
That is, how to estimate a VAR models with some conditions imposed on the
parameters estimated?

Yes, it's intended. The residuals we report from WLS are the same
as those reported by R. They represent the deviations of actual y
from the predictions for y generated by the coefficients of the
weighted model applied to actual X.
The following script illustrates the point.
<script>
open data4-1
series w = 1/sqft
wls w price 0 sqft
series u1 = $uhat
series chk1 = price - ($coeff[1] + $coeff[2]*sqft)
series ystar = price/sqrt(sqft)
series cstar = 1/sqrt(sqft)
series xstar = sqft/sqrt(sqft)
ols ystar cstar xstar
series u2 = $uhat
series chk2 = ystar - ($coeff[1]*cstar + $coeff[2]*xstar)
print u1 chk1 u2 chk2 -o
# compare R, if available
foreign language=R --send-data
y <- gretldata[,"price"]
x <- gretldata[,"sqft"]
w <- gretldata[,"w"]
model <- lm(y ~ x, weights=w)

end foreign

comparing two models
by remi sorama
Dear all,
I have a gretl session with four variables: y1,x1,y2,x2 and also two
regression models of y's on respective x's. I would like to compare these
two models with the Chow test, but it seems I have to reorganize my data
into two long vectors of y and x first. How can I do it?
Or isn't it the same as solving these two equations as a system and
applying Tests -> Linear restrictions, typing b[1,1]-b[2,1]=0 etc?
And what if I have not two but three firms?
Many thanks,
Rem
